As explained in

 http://docs.racket-lang.org/pkg/getting-started.html

you can install a package with either DrRacket or with `raco pkg` at
the command line.


In DrRacket:

 * Select "Package Manager" from the "File" menu

 * Type "memoize" in the text field

 * Click "Install"

Or at the command line:

 raco pkg install memoize


After either of those, searching documentation "memoize" should work,
and the docs say to use

 (require memoize)

and then `define/memo`.


> Also, how do I then delete the old "planet" - based memoize?

At the command line:

 raco planet remove dherman memoize.plt 3 1
